What happens when you're stuck between a rock and a hard place and your brother is involved... NYPD Homicide detectives Carrie Blake and Tom Elway have a talent for finding serial killers. Since they’ve been partnered up two years ago, they’ve taken down four. But these days, New York City’s gotten harder, its shadows longer and darker—and more and deadlier killers are stalking its streets. These two cops—one a third-generation cop who loves law and procedure, the other a maverick who barely toes the line—are the best of the best, chasing the worst of the worst. And this time, the trail is going to lead them way too close to home for Carrie’s comfort. Her decorated older brother Carl hasn’t been the same since his partner Benny was brutally attacked by a perp while on duty. When a series of vigilante-style murders rocks Manhattan, the trail leads straight to Carl. Caught between family loyalties and loyalty to the law, Carrie can’t deny the evidence. The deeper they dig into this case, the uglier the story gets—one of broken dreams, betrayal, revenge, ritualized murder, and a terrifying drug known as the Devil’s Breath. Can they uncover the truth before more people die, or will the devil they chase steal their very lives? An incredible edge of your seat page turner that will have you guessing right til the very end.
